Title: Improvements in or relating to a method of blending masses and devices for performing the same
IPC: B01F29/64
Filed: 1957-12-02
Abstract: 837,345. Mixing. COSMETTO, A. J. Dec. 2, 1957, No. 37520/57. Class 86 Mixing of powdered and similar materials is done by subdivision in threearmed container 36, 37, 38, rotated intermittently about an axis perpendicular to the plane of the arms. A motor 50, through a reduction gear 51, drives a pinion 54 and gear 66, the latter of which has an extension 67 carrying a shaft 68 by means of which a pinion 69 is carried around a stationary gear 59. An offset crank pin 72, rigid with the pinion 69, carries a roller 75 running in a guide channel in a radial member 58, which is mounted on the same shaft 39 as the containers 36, 37, 38. The motion of the pin 72 and roller 75 causes the containers to be rotated through 120 degree steps with a momentary pause at the end of each step and, at each pause, one arm is held vertically upwards so that its contents fall and are approximately equally divided between the other two arms. The gear 59, which is normally stationary, is mounted on a slave at the other end of which is a disc 62, normally held by a pin 103 engaging in a suitable recess. If, however, the pin is withdrawn, the gear 59 is free to rotate and, under such conditions, the assembly of gear 59, pinion 69 and arm 58, rotates as a whole and the containers are rotated continuously. The whole of the mechanism for rotating the containers is carried on a plate 25, which can be tilted about a pivot bolt 24 by a worm 23 and sector 28, so that the plane, in which the containers are rotated, can be varied. The Specification also describes a modified form of apparatus in which intermittent rotation is achieved by means of a Geneva detent mechanism.

Title: Improvements in or relating to fuel injection systems for internal combustion engines
IPC: F02D41/30
Filed: 1958-11-26
Abstract: 904,461. Electric control systems. BOSCH G.m.b.H., ROBERT. Nov. 26, 1958 [Nov. 27, 1957], No. 38054/58. Class 40 (1). [Also in Groups XXVII and XL (c)] The fuel injection valve of an I.C. engine is opened during the unstable state of a monostable transistor flip-flop circuit which is changed over once per revolution for each cylinder by a cam driven by the engine shaft, and returns to its stable state after a time period determined by the speed of the engine, the position of the throttle lever, and the temperature and pressure of the air. As shown (Fig. 1), the valve cone 35 of a fuel injection valve 33 is raised to allow fuel to be injected into the intake pipe 30 of an I.C. engine 10 when coil 34 is energized by the output of an amp ifier 28, which occurs when normally conducting transistor T 2  is cut off by transistor T 1  conducting after switch 39 has been closed by cam 38 driven by the motor shaft 11. The duration of the cut-off is determined partly by the potential at the emitter E 2  of transistor T 2  and partly by the discharge time of capacitor 58 through its shunt resistors 59, 60, resistor 59 being sensitive to atmospheric temperature and pressure. Motor shaft 11 drives a second cam 25 to cyclically close a switch 27, when capacitor 76 is charged through the emitter-base path of transistor T 3 , and capacitor 78 is also simultaneously charged, to be discharged through a potentiometer resistor R when switch 27 is open. Since the charging time of capacitor 78 is determined only by the values of capacitor 76 and resistor 77, and is therefore constant, and its discharge time depends on the period between successive closures of switch 27, the average voltage across capacitor 78, and potentiometer R, is higher at higher motor speeds, and thus reduces the time during which transistor T 2  is non-conducting, and valve cone 35 is raised. The voltage at the emitter Eg is further controlled by the position of the slider of potentiometer R, which is mechanically linked to the throttle lever 81.

Abstract: 909,441. Parallel-mode digital computers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 19, 1960 [Nov. 26, 1958], No. 38193/58. Class 106 (1). In a parallel-mode digital computer, equipment is provided at one or more positions spaced along the arithmetic unit to inspect the information supplied to one or more successive digit stages, e.g. stages n to n + 3, to determine whether or not the propagation of a carry-over digit would be obstructed at the selected position ; and to vary the settling time accordingly. For addition of two numbers A, B, carry-over propagation is obstructed if corresponding digits of A and B are equivalent, and if this occurs at an inspection position one or more of signals C 1- C 4  derived from A,A, B,B will be a " 0 ", output of gate G 1  will also be " 0 " and output D will be " 1." The total possible carry-over propagation time is thus known and the settling time may be selected accordingly. Similarly for subtraction of A, B carry-over propagation is obstructed if corresponding digits of A and B are non-equivalent, and if this occurs at the inspection position one or more inputs to gate G 2  are " 0 " and again a " 1 " is obtained at D.

Filed: 1929-12-16
Abstract: 344,941. Clockwork-actuated valves and electric switches. HORSTMANN GEAR CO., Ltd., Newbridge Works, and HORSTMANN, A., 2, Newbridge Hill, both in Bath. Dec. 16, 1929, No. 38411. [Class 135.] A clockwork tappet-operated gas controller which, according to the Provisional Specification, is applicable also to electric switches, is provided with a pair of gas-cock operating levers 11, 14 interconnected so that, as one lever is moved by a tappet out of the tappet path in order to operate the cock, the other lever is moved by the first lever into the tappet path, the levers 11, 14 being operated, respectively, by rotating ON and OFF tappets 5, 4 which are situated in different planes. The gas cock 6 is detachably mounted on the clockwork casing 7 in the manner described in Specification 189,476, [Class 135, Valves &c.]. The ON lever 11, which is two-armed, is secured to the plug 10, the arm 11 being arranged so that in the closed position of the cock it projects into the path of the tappet 5, and the arm 12 being provided with a slot 17 engaged by a pin 13 on the OFF lever 14 which is fitted over the lever 11 and pivoted at 15 to the casing by a pin 16. The OFF lever 14 is arranged so that it projects into the path of the OFF tappet 4 when the cock is in the open position. A spring 18 secures the plug from rotation due to mechanical vibrations &c. In operation, in the ON position shown in Fig. 1 the OFF tappet rotates and, at a predetermined time, contacts with the OFF lever 14 to rotate the plug into the closed position, at the same time the ON lever 11 is rotated in the opposite direction to the lever 14 and enters the path of the ON tappet 5. The reverse action occurs when the ON tappet 5 contacts with the ON lever 11. In place of the pin and slot connection 13, 17 between the levers 11, 14 in Figs. 1 and 3, a stud 13, Fig. 5, passing freely through a shouldered sleeve 19 which moves in a slot 20 in the lever 14 may be provided, said stud 13 being fixed to the arm 12 of the ON lever. Two OFF tappets having different radii may be provided for controlling two or more burners, the automatic extinguishing of the burners, in order, being obtained by suitable porting of the gas cock as described in Specification 293,714, [Class 135, Valves &c.], and by the pins of the OFF tappets being arranged so as to rotate the OFF lever, first, partially, and then wholly. Means for extinguishing and retaining the byepass may be provided by suitable porting of the cock. Since the ON and OFF tappets are in different planes, any disturbance of the position of the gas-cock with respect to the tappets 4, 5 will not alter the sequence of the operations.

Filed: 1974-08-08
Abstract: 1478140 Character recognition systems EMI Ltd 8 Aug 1974 [11 Aug 1973] 38792/73 Heading G4R The output of a scanner viewing an unknown character is processed to resolve it into signals representing a number of arcs which approximate the shape of the character. Each arc is compared with each arc of sets of component arcs, each set representing a reference character as in Specification 1,333,916. The position of the centre of the unknown character is predicted on the basis of each comparison. If an arc of the unknown character does not match an arc of a reference character sufficiently well the corresponding prediction is ignored. If the predictions resulting from the comparisons with a given set lie within an area of predetermined size it is assumed that the unknown character is the same as the corresponding reference character. By consideration of the distance between the predicted centres of adjacent characters it can be decided whether the characters belong to the same group (e.g. 37) or separate groups (e.g. 3, 7). Extrapolation of a line joining the centres of two characters may be used to predict the approximate position of the next.

The fingers are either above, or below the 1-5 Á thick piezo film, Figs. 3, 2 (not shown), or the fingers and a gold counter electrode (5), Figs. 4, 5 (not shown), may sandwich the piezo film. For suitable choice of substrate glass, the effect of temperature variation of delay due to the transducer structures can also be compensated. The device can be connected between the input and output of a broad band amplifier (not shown), whence the frequency of oscillation depends only on the phase change through the transducers and substrate, leading to an oscillator stable to less than 1 p.p.m. Exemplary transducer dimensions are disclosed.
